Definitions
- the present invention relates to a segmented roll comprised of a plurality of end-to-end mounted roll segments, each adapted to rotate on bearings supported on a separate support shaft.
- the bow of such a segmented roll can be changed by adjusting the position and/or distance of the support points of the individual roll segments in regard to their mounting frame, thus making the roll extremely suitable for use, e.g., as a spreader roll in conjunction with the handling of a web-like continuous sheet of material.
- the segmented roll is also suited for use, e.g., as a guide roll for a paper web or as a pressure roll in winding.
- each of the roll segments is generally joumaled at its both ends on bearings which are supported on the segmented roll mounting frame or similar support framework. Frequently, two adjacent roll segments share one bearing unit. Then, removal of one roll segment from the central area of this kind of segmented roll may be difficult, because the segmented roll must be disassembled starting from one end in order to reach the roll segment to be replaced at the central area of the segmented roll.
- each stub shaft is provided with a separate support bearing that is designed to function as a pivotal bearing point.
- the pivotal bearing points of the abutting stub shafts are adapted in close proximity to each other on the different sides of the support bearing, whereby each support bearing unit supports one of the adjacent pivotal bearing points.
- This kind of a two-part support bearing block makes it possible to dismount and replace separate roll segments without the need for complete disassembly of the entire spreader roll.
- such an arrangement places two bowing points at a small distance from each other thus causing nonuniform bowing of the roll.
- the bowing point is not exactly at the mating point of the abutting roll segments, but rather, displaced by a small distance therefrom, the bend of the roll tends to lift up the end of the roll segment and thus makes the roll rotate bowed into a toothed shape.
- the correct geometry of roll bow is not attained which causes problems in controlling the web travel.
- segmented roll according to the invention is characterized by what is stated in the characterizing part of claim 1.
- the segmented roll according to the invention has coupling means adapted to both axial end surfaces of the support shafts of its roll segments, said coupling means serving to disengageably connect two adjacent roll segments to each other.
- the support shaft contains at least two parts such that changing the mutual disposition of said parts makes it possible to alter the axial length of the support shaft.
- the coupling means on the support shaft end surfaces are such that allow a coupling to be established between two adjacent roll segments, the coupling being capable of accommodating an inclination between the longitudinal axes of the adjacent roll segments.
- the coupling means may contain a projection or the like on the end surface of the first roll segment and a mating recess on the end surface of the second roll segment.
- the projection can be formed, e.g., by an annular flange projection made to the end surface of the support shaft with a shape allowing limited rotation and inclination of the projection in a concentric annular recess made to the end surface of the adjacent roll segments when the adjacent roll segments are coupled to each other.
- one of the mating coupling surfaces may be formed by a concave hemispherical surface, whereby the mating end surface is formed by a convex hemispherical surface.
- the support shaft of the roll segment is comprised of two parts adapted to be solidly, advantageously nonrotatably, lockable to each other with the help of a locking element. After the locking element is released, the shaft parts can be axially moved with respect to each other by a distance allowing the coupling means formed on the mating end surfaces of the abutting roll segments to be withdrawn apart from each other.
- the first part of the support shaft includes an axial projection, most advantageously like a peg that is adapted to fit into an axial bore of the second part of the support shaft.
- the locking element can be a fastening member, advantageously a lock screw, placed into a radial hole made to one end of the support shaft, the tip of the locking element in its locking position being adapted to press against the outer circumference of the support shaft axial projection thus being capable of solidly locking both parts of the support shaft to each other.
- the lock screw or similar locking element also has another functional position.
- the length of the lock screw is advantageously made such that when the lock screw is turned away from resting against the outer circumference of the axial projection, the screw head will tuck against the inner circumference of the roll segment shell thus coupling the other part of the support shaft to follow a possible movement of the roll segment shell.
- the inner circumference of the roll segment shell is advantageously provided with a recess suitable for assuring positive contact of the screw head with the roll segment shell when the roll segment is being rotated.
- At least a portion of the axial projection part and the axial recess part connecting the abutting parts of the support shaft to each other have compatible outer and inner threads, respectively, made thereto.
- the roll segment of the segmented roll according to the invention is comprised of an outer shell and an inner shell connected to each other by a disc portion. Both parts of the support shaft are provided with an annular recess opening toward the interior of the roll segment, said recesses being adapted to accommodate the tubular flange parts of the inner shell extending to both sides from said disc portion.
- Each roll segment is rotatably mounted on the support shaft preferably using two bearings, advantageously ball bearings, having their inner races fixed to the rotating inner shell of the roll segment and their outer races fixed to the inner surfaces of the outer walls of the annular recesses made to the support shaft.
- the segmented roll comprises a plurality of roll segments having their support shafts mounted only at one end on the mounting frame of the segmented roll, complemented with one roll end segment having its both ends mounted on the mounting frame.
- the mounting arrangement of the support shaft end on the frame is advantageously such that allows the position on and/or distance of the roll segment end to be adjusted in regard to the mounting frame.
- segmented roll embodiment it is possible to replace any single roll segment in the central area of the segmented roll without the need for complete disassembly of the entire segmented roll assembly.
- only one end of each roll segment is mounted on the segmented roll mounting frame, while the other end is supported on the adjacent roll segment by means of a coupling that can be disengaged through adjusting the support shaft of the roll segment to a shorter length.
- the segmented roll will bow evenly without any toothed jaggedness in its curvature.
- the segmented roll is unproblematically suited for supporting a web, for instance.
- the segmented roll schematically illustrated therein comprises five roll segments 10 in an end-to-end succession, whereby the first four of the roll segments are mounted by their one ends via a support member 23 on a mounting frame 5, while their other ends are supported on the end surface of the respective adjacent roll segment 10.
- the last roll segment 10' of the row of roll segments has both of its ends mounted on the mounting frame 5.
- Each of the roll segments 10 has a nonrotating support shaft of its own, on which it is adapted to rotate on bearings.
- the coupling between two adjacent roll segments 10 is adapted to permit a limited angle of inclination between the end-to-end adjacent roll segments 10.
- the mounting of the roll segments 10 on the mounting frame 5 is made such that allows the position of any single roll segment 10 to be adjusted both in regard to its height as well as its lateral disposition thus making it possible to adjust the bow of the segmented roll in an uncomplicated manner.
- Each roll segment 10 is comprised of two concentric cylindrical shell parts 12 and 13 connected to each other by a disc portion 14 situated in the central symmetry plane of the cylindrical shell parts.
- the roll segment 10 is advantageously made by casting.
- the outer cylindrical part 12 forms the shell proper that in a segmented roll serving as a spreader roll advantageously has a grooved outer surface.
- the inner cylindrical shell part 13 has a length shorter than that of the outer shell part 12 and has the support shaft 11 of the roll segment adapted to pass therethrough.
- the support shaft 11 of the roll segment is formed by two flange-like parts that are later in the text denoted as an intermediate support member 16 and an intermediate connection member 18. These members 16 and 18 are adapted into the interior space of the roll segment 10 so that the surfaces of the intermediate support member 16 and the intermediate connection member 18 directed axially outward from the center of the roll segment 10 serve as the end surfaces of the roll segment 10 and, additionally, as the mating surfaces in the coupling between two adjacent roll segments.
- the two parts of the support shaft 11 are connected to each other by a stub shaft 17 that is incorporated in the intermediate support member 16 and has a length extending through the inner shell 13 of the roll segment into the center bore 19 of the intermediate connection member 18. In the normal position of the assembly serving the operation of the segmented roll, the support shaft members 16 and 18 are locked to each other nonrotatingly by means of a lock screw 36.
- the intermediate support member 16 is mounted on the mounting frame 5 of the segmented roll via a support member 23 which may be separate from or integral with the intermediate support member 16.
- a support member 23 which may be separate from or integral with the intermediate support member 16.
- FIG. 1 are schematically shown the fastening and adjustment means 21,22 associated with the support member 23, advantageously implemented by means of adjustment screws that facilitate the position adjustment of the intermediate support member 16 both vertically and laterally in regard to the segmented roll mounting frame 5.
- This arrangement permits the bow of the segmented roll to be controlled by adjusting the position of any roll segment 10 separately in regard to its adjacent roll segments.
- a stub shaft 17 having an annular recess 27 surrounding its base projects from the center of the disc-like portion of the intermediate support member 16 in the direction of the interior space of the roll segment 10. This recess serves to accommodate the tubular flange part of the inner shell 13 of the roll segment 10 projecting toward the intermediate support member 16. In the axial direction, the stub shaft 17 extends through the bore of the inner shell 13 of the roll segment 10 close to the other end of the roll segment 10.
- the outer end of the stub shaft 17 has a portion 30 with male thread 32 and there is a flattened area 31 arranged in the perimeter of said threaded portion (see FIG. 3).
- the intermediate connection member 18 located on the other side of the roll segment 10 functions as a mating member to the intermediate support member 16 so that said members 16,18 together form a support shaft 11 of the roll segment 10.
- the intermediate connection member 18 is shaped into a disc-like piece having a sleeve portion 33 projecting from its center toward the interior space of the roll segment.
- the sleeve portion 33 has an annular recess 34 made at its base serving to accommodate the tubular flange part of the inner shell 13 of the roll segment 10 projecting toward the intermediate connection member 18.
- the axial bore 19 of the sleeve portion 33 extends through the entire length of the intermediate connection part 18 up to the terminal end of the sleeve portion.
- Both the stub shaft 17 of the intermediate support member 16 and the sleeve portion 33 of the intermediate connection member 18 have an outer diameter slightly smaller than the inner diameter of the inner shell 13 of the roll segment 10, thus avoiding any direct contact between the inner shell 13 with the parts 17 and 33 of the support shaft 11 passing therethrough.
- a lock screw 36 acting as a locking means that has two functional positions. In the first position of the screw 36, its tip that is directed toward the longitudinal axis of the roll segment is driven tightly against the flat area 31 on the periphery of the terminal end 30 of the stub shaft 17. Then, the screw 36 serves to lock the intermediate connection member 18 solidly to the stationary intermediate support member 16 so as to prevent rotation of the intermediate connection member 18.
- the cap end of the lock screw 36 that is directed radially outward from the stub shaft is provided with a bushing 37 adapted to meet the perimeter of the intermediate connecting member 18 about the hole 35 when the tip of the lock screw 36 is compressed against the flat area 31 of the stub shaft 17.
- the perimeter of the intermediate connection member 18 can be machined to have a partially flat key area (not shown) extending about the hole 35, whereby the bushing 37 can evenly rest on said flat key area.
- At least that portion of the axial bore 19 of the intermediate connection member 18 which extends from the hole 35 up to the outer end surface of the intermediate connection member 18 is provided with an inner thread 42 compatible with the outer thread 32 of the terminal end 30 of the stub shaft 17 of the intermediate support member 16.
- the roll segment 10 is rotatingly mounted on two ball bearings 20 running on the support shaft 11 formed by the intermediate support member 16 and the intermediate connection member 18.
- the bearings are adapted to both sides of the disc portion 14 of the roll segment 10, on the outer surface of the inner shell 13 so that the inner races of the bearings 20 rotate with the inner shell 13.
- the inner shell 13 is formed by two tubular flange parts which extend to both sides from the disc portion 14 and are enclosed by an annular recess 27 on the side facing the intermediate support member 16 and by a respective annular recess 34 on the side facing the intermediate connection member 18.
- the stationary outer races of the bearings 20 are then supported on the inner surfaces of the outer walls of these two annular recesses 27 and 34.
- the inner surface of the inner shell 13 of the roll segment 10 has no direct contact with the members 17,19 of the support shaft 11 passing through the bore of the roll segment's inner shell 13.
- the bearings 20 are the only point at which the roll segment 10 is connected to the support shaft 11.
- the chief function of the stub shaft 17 of the intermediate support member 16 together with the sleeve portion 33 of the intermediate connection member 18 fitted into the central bore of the inner shell 13 is to form the coupling elements for connecting the support shaft members 16 and 18 to each other.
- FIG. 4 is shown the structure of the last roll segment 10'.
- its support shaft 11' is comprised of the above-described standard-type intermediate support member 16 connected to an end support member 16', whose structure combines certain characteristic details of the standard-type intermediate support member 16 and those of the intermediate connection member 18.
- the coupling means for connecting two adjacent roll segments 10 to each other are formed on the end surfaces of the support shaft 11 of the roll segment.
- the outer surface of the intermediate support member 18 has an annular flange projection 41 made thereon, while the outer surface of the intermediate connection member 16 has an annular groove 29 made thereon with a shape essentially concentrically compatible with that of the annular flange projection 41.
- the universal joint between two adjacent roll segments 10 is formed between the end surfaces of the first roll segment's intermediate connection member 18 and the second roll segment's intermediate support member 16.
- the annular flange projection 41 made to the end surface of the first roll segment's intermediate connection member 18 enters the annular recess 29 made to the end surface of the second roll segment's intermediate support member 16, wherein it can rotate and tilt within the limits provided by a suitably arranged play.
- the maximum inclination can be increased by proper beveling of the edges of the annular flange projection 41 and the annular recess 29.
- the segmented roll can bow without any jaggedness between two adjacent roll segments 10.
- the first step comprises unscrewing the lock screw 36 of the support shaft 11 that fixes nonrotatingly the intermediate connection member 18 to the intermediate support member 16 of the roll segment.
- the outer shell 12 of the roll segment is provided with an opening 39 drilled in a position coinciding with the head of the lock screw 36 and having a recess 40 made about said opening on the inner surface of the outer shell 12 of the roll segment (see FIG. 3).
- the unscrewing of the screw 36 can be performed by inserting through the opening 39 a tool by means of which the lock screw 36 is rotated until the head 38 of the lock screw meets the recess 40 made to the inner surface of the roll segment's outer shell 12.
- the tip of the lock screw 36 has been released from the contact with the stub shaft 17 of the intermediate support member 16 and the head of the lock screw 36 has locked intermediate connection member 18 to rotate with the outer shell 12.
- the roll segment 10 can be rotated in a proper direction by a suitable number of turns depending on the pitch of the threads 32,42 so that the intermediate connection member 18 rotates with the roll segment 10.
- FIG. 5 is shown another embodiment of the roll segment suitable for use in a segmented roll and particularly the connection members of the roll segment.
- the structure of the roll segment is chiefly identical to that of the roll segment shown in FIG. 2.
- the connection members comprise a projection 45 formed by a convex hemispherical surface on the end surface of the intermediate connection member 18 and, on the end surface of the intermediate support member 16, a recess 46 having the shape of a concave hemispherical surface which is essentially concentric and of equal radius of curvature with that of the mating end surface formed by the projection 45.
- the coupling elements at the end surfaces of the roll segments are concentric members, whereby the release of the support joint between the adjacent roll segments can be arranged to take place by rotation.
- the coupling member may be, e.g., a threaded bushing attached to the end of the intermediate support member stub shaft and arranged to fit into a recess made to the end surface of the adjacent roll segment when the roll segments are in their coupled position. Then, the entire body of the intermediate support member need not necessarily be movable toward the support member of the roll segment, but instead, the contraction of the support shaft length can be simply accomplished by rotating the threaded bushing along the roll segment support shaft toward the support member.
